Elasticsearch refuses to run

Elastic Stack Elasticsearch
1

I've installed the .tar.gz package on a Rhel7.5 instance on Amazon Web Services with a RAM of 1GB and volume of 10GB but when I run it with this command "./bin/elasticsearch" I get this error despite reducing the heap size to 512MBs:

Exception in thread "main" java.nio.file.AccessDeniedException: /elasticsearch-6.3.1/config/jvm.options at sun.nio.fs.UnixException.translateToIOException(UnixException.java:84) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:102) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:107) at sun.nio.fs.UnixFileSystemProvider.newByteChannel(UnixFileSystemProvider.java:214) at java.nio.file.Files.newByteChannel(Files.java:361) at java.nio.file.Files.newByteChannel(Files.java:407) at java.nio.file.spi.FileSystemProvider.newInputStream(FileSystemProvider.java:384) at java.nio.file.Files.newInputStream(Files.java:152) at org.elasticsearch.tools.launchers.JvmOptionsParser.main(JvmOptionsParser.java:58)
What could the issue be?

How did you install Elasticsearch?

3

I installed using the .tar.gz option

4

Right, but what did you do exactly?
What commands, what user?

5

I installed using root and the commands were as follows:

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz.sha512 shasum -a 512 -c elasticsearch-6.4.0.tar.gz.sha512 !(https://www.elastic.co/guide/en/elasticsearch/reference/current/images/icons/callouts/1.png) tar -xzf elasticsearch-6.4.0.tar.gz cd elasticsearch-6.4.0/ !(https://www.elastic.co/guide/en/elasticsearch/reference/current/images/icons/callouts/2.png)

this is the link to the guide i followed...https://www.elastic.co/guide/en/elasticsearch/reference/current/zip-targz.html

7

What user are you trying to run Elasticsearch as?

8

ec2-user currently coz i tried running the process using root but it keeps on being killed

9

You cannot run Elasticsearch as root, ever, there are checks to stop that.

Which would probably explain this;

Why not use the rpm?

10

Does that mean reinstalling elasticsearch with rpm?

11

Yes, that creates the proper directory structures, users and service files.

12

can i uninstall the .tar.gz version?

13

Just rm -rf the directory you extracted.

Also, ideally, you should setup the repo, not just download the RPM. That way you are setup to allow easy upgrades as well.

14

Okay, do you think this guide will help me?...https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html

15

Yep!

16

Thanks Mark you are awesome

Check /var/log/elasticsearch for something.
